Hematopoietic System NCLEX Questions
and Answers | Latest Update
A nursing student wants to know why clients with COPD tend to be polycythemic. What

response by the nurse instructor is best?

a. It is due to side effects of medications for bronchodilation.

b. It is from overactive bone marrow in response to chronic disease.

c. It combats the anemia caused by an increased metabolic rate.

d. It compensates for tissue hypoxia caused by lung disease.

✓ -:- D ~ In response to hypoxia, more red blood cells are made so more oxygen

can be carried and delivered to tissues. This is a physiologic process in response to

the disease; it is not a medication side effect, the result of overactive bone marrow,

or a response to anemia.




What is the normal lab value for Platelet Count?

✓ -:- A normal platelet count ranges from 150,000 to 450,000 platelets per

microliter of blood. Having more than 450,000 platelets is a condition called

thrombocytosis; having less than 150,000 is known as thrombocytopenia.




A client is receiving rivaroxaban (Xarelto) and asks the nurse to explain how it works. What

response by the nurse is best?

b. It inhibits fibrinogen.

c. It thins your blood.

d. It works against vitamin K.

✓ -:- A ~ Rivaroxaban is a direct thrombin inhibitor. It does not work on

fibrinogen or vitamin K. It is not a blood thinner, although many clients call

anticoagulants by this name.




What is the normal lab value for Red Blood Cells (RBC)?

✓ -:- Men = 4.7 to 6.1 million cells per microliter (mcL). Women = 4.2 to 5.4

million mcL.

Children is 4.0 to 5.5 million mcL.




The health care provider tells the nurse that a client is to be started on a platelet inhibitor.

About what drug does the nurse plan to teach the client?

a. Clopidogrel (Plavix)

b. Enoxaparin (Lovenox)

c. Reteplase (Retavase)

d. Warfarin (Coumadin)

✓ -:- A ~ Clopidogrel is a platelet inhibitor. Enoxaparin is an indirect thrombin

inhibitor. Reteplase is a fibrinolytic agent. Warfarin is a vitamin K antagonist.

What is the normal lab value for White Blood Cells (WBC)?

✓ -:- 4,000 - 11,000 per microliter of blood




A nurse is assessing a dark-skinned client for pallor. What action is best?

a. Assess the conjunctiva of the eye.

b. Have the client open the hand widely.

c. Look at the roof of the client's mouth.

d. Palpate for areas of mild swelling.

✓ -:- A ~ To assess pallor in dark-skinned people, assess the conjunctiva of the eye

or the mucous membranes. Looking at the roof of the mouth can reveal jaundice.

Opening the hand widely is not related to pallor, nor is palpating for mild swelling.




What is the normal lab value for Hemoglobin (Hgb)?

✓ -:- Men = 13.5 - 17.5 g/dL

Women 12.0 - 15.5 g/dL




A hospitalized client has a platelet count of 58,000/mm3. What action by the nurse is best?

a. Encourage high-protein foods.

b. Institute neutropenic precautions.

c. Limit visitors to healthy adults.

d. Place the client on safety precautions.
